Specifically , a 2005 E320 sedan. Can someone tell me if there are any real differences between a W210 2001 E320 and a W211 2005 E320? They seem to have the same engine and transmission.

Thanks!

The W211's have fuel tank problems.

My W211 E55 is the best car I have ever owned, on many of the car boards the fuel tank and AirMatic are the most common complaints. The W211 E320 in most cases dose not have AirMatic.

Actually they are quite different engines, the newer (2005+) having 4 valves/cyl, twincam, single plug, 20% more HP;

M112 (1997 - 2004 E320)
228 lb-ft @ 5700 rpm
214 hp @ 5700 rpm
ME 2.8
Sparkplugs per cylinder 2
Double ignition coils
Compression Ratio 10.0 : 1
3.2 liter

M272 (2005+ E350)
258 lb-ft @ 2500 to 5000 rpm
268 hp @ 6000 rpm
ME 9.7
Sparkplugs per cylinder 1
Coil On Plug
3.5 liter

Another small difference is the addition of an automatic headlight setting.

no, they are the same engine. 2005 e320 in north america market still had the m112 engine. it wasn't until 2006 that e350 came with the m272 engine.

the main difference between the 2001 m112 and 2005 m112 is the disappearance of oil dipstick and usage of 2 air filters (one per bank) instead of 1. you can check the oil level via control buttons in steering wheel. the air box is also the engine cover (similar setup like in m119), so you need to remove the 2 air ducts and lift up the engine cover to access the air filters, where in 2001 e320 the air filter box is on passenger side.
also 2005 e320 will have the sensotronic brake control (sbc brakes).

I am picking up W211 in a week, I did notice quite different cover, but hope at least the transmission is exactly the same
I am getting tired of learning new technology every few months
If you want W211 get yourself familiar with SBC brakes, there is million times more myths about them, than real issues, so you have to figure it out.

Ahhh, I see. I was confused by the OP of "2005 E350", silly me.

We're all doomed here.

The W211 wagon is coming as extra vehicle with potential to replace wife's aging W210, but son's W210 will not be replaced at least till he graduates from college

C'mon, I have had mine for only 2 years and it is only 15! Define 'aging'

 

[Kajtek1]

Define 'aging'

2 dings and 3 scratches
For me another car usually means I have time and money to spare. All diesel MB I brought to California sold for more than I paid for them. I am not counting cost of driving them here obviously, but loading Polish food and beer in Chicago pays for that. The new wagon is gasser as diesels never made it here, but I will have good use for wagon and what really kick me in this one are dynamic seats with ventilation.
Wagon 4-Matics have good resale value on West Coast as well, so it is kind of investment.
Did I say I love driving?

 

[shingleback]

Great, now you are making me jealous! I could co-pilot for you, as long as you share that Polish food. Your reasons make sense, but I will have to visit your stable on one of my trips south. I am hoping to drive the E300 down to Sac/Modesto after winter.

Thanks for all the information, everyone. It helps out quite a bit. My wife and I went to look at the car and only drove it 100 feet before turning around. Something was definately wrong with the front suspension. Also, the interior of the W211 appears noticably smaller than the W210 which was disappointing.

We went down the street to the MB dealership and looked at a 2006 S430. Very nice, but my wife wants a 6 cylinder. Not many S350 cars around here, though. I'm really only interested in getting her an MB if the car is as easy to work on as my E320, but she doesn't want a car as old as a W210.

Does anyone know if the 2006 S350 (W220) is as easy to do DIY fixes as the W210 E320?

My E320 has a 112.972 engine and the S350 has a 112.941 engine. Does anyone know the similarites/differences between the two? Since I know the 112.972 engine, it would be nice if the 112.941 was similar for repairs, understanding it, etc.

If you have any first hand knowledge you can share about a 2006 S350, I would appreciate it.

thanks!

One of my dream cars is the 2006 S350. The dealer had a couple coming off a lease but I didn't have the money at the time (still don't). Those are pretty rare as they only made them the one year but the engine ran a few years in the ML350. Keep your eye on AutoTrader and you will see a few.

When you are buying used Mercedes and you zoomed on particular model you have to be ready to travel and often travel far.
S is having the same drivetrain what E with the same engine, but has lot of other gadgets that can cost you a fortune if they start failing and more and more electronics require Star computer to diagnose.

Wrong the 350 is not a M112 engine, you might want to reread this thread as a previous post has answered this 320 vs 350 question. One other thing you should do, is a search for the gear failures in the 350 & 550 engines, those have problems.

Here is one,

I'm not sure you would find me in a W220 Benz. Now a W221, it's at least sexy enough to deal with the issues.

I'll echo what Kajtek said about the complexity of the S versus a similar period E, it's at least an order of magnitude more complicated. If you have the budget to maintain it like an airplane, you'll be fine. But there are so many little this and thats attached that it doesn't take long before you're thinking ... hmmm that Prius my neighbor has sure looks good.

I LOVED my W210, S420. Just a wonderful car, even given the biodegradable engine harness. But I also love working on these cars, so buying $65 of aircraft grade wiring and rewiring the harness just made for cool project time with my sons. After six years and lots to fix, I was just out of time to keep up with it all.

@Yacht: Thanks for the link. The link refers to the M272 engine (and others but not the M112). I'm looking at two different MY2006 S350 cars. The VIN number on both, when entered into WIS and also this VIN lookup site says it is:

Sales Designation: S350
Model designation: 220.067
Engine: 112.972
Major assembly: AG 722.644 W 5 A580

The MY2006 S350 V6 is a 3.7 liter, so that would indicate an M112 M37. An M272 would indicate an E35 which is a 3.5 liter - which it is not.

The carfax on both seem to indicate that valve cover gaskets were replaced. Funny since I ran into that issue 2-3x on my W210 M112.

p.s. I always smile when I see your avatar-in-motion

@Kajtek1: Thanks for that information. The S-series forum has a pretty good DIY link list. I'll check that out and see what electronics have been failing. I hate that the STAR diagnostics would need to be used to diagnose. Good food for thought. Not sure how to process that except to look for a used STAR system. On a few other threads, I've asked what STAR offers that CarSoft doesn't. Is it pinpoint diagnostic part isolation? I assume that it does more than read the codes? thanks!!

Todd,

The early ones had a battery of transmission problems with the 722.9. Most were software issues, and require software upgrades. The other issue is damaged oil pumps in the transmission. Which I think the pump torque values are less than a 722.6, yet the pump and torque converter are the same as 722.6..

They are beautiful cars, but the tranny issues are scary..
